To ail 'iv/0m t may concern:

Be it known that I, HERBERT T. hSunnn, a. citizen of the United States, residing at Baltimore, in the State of il'laryland, have invented certain new and useful In'iprovements m Bottle-Sealing Machines, of which the following is a full, clear, and exact speei-- ica'tion.

This invention relates to bottle capping machines and has special reference to the mechanism for feeding the caps to the sealing head, the object of the invention being to provide an apparatus of simple construc tion and arrangement by which the caps will be fed automatically and which, upon failr ure of the sealing head to act upon the cap 1 fed thereto, will automatically suspend the feeding process until normal conditions are views z-F igure 1 is a front elevation of the upper portion of a bottle capping machine 1 embodying my invention; Fig. 2 is a similar view of the feeding mechanism on a larger scale; Fig. 3 is a side elevation of the upper portion of the. bottle capping' machine; Fig. l is a similar view on a larger scale of the feeding mechanism; and Fig. 5 is a detail sectional fiew, showing the loop lever which directly actu ates the feeding finger, the sh aft on which it is mounted, the roller which rides over said lever, and the yoke on the. opposite end of said shaft. l

The standard 1 is of the usual form and the sliding bar 2 is mounted in the upper end of the same, said bar being formed with a. lateral arm or bracket 3 to which is secured lthe sea-ling head 4. A hopper 5 is supported from the bracket 3 and a chute 6 leads from said hopper to convey-the caps to and into the lower end of the sealing head, said chute being longitudinally slotted in its outer side.

Secured upon the front of the sealing head, above the lower end thereof, are brackets forming bearingsi, 8, a shaft 9 being jonrnaled in the bearing 8 and a leveri`10 being pivotally supported in the bearing 4.

Thelower portion of this lever l0 is laterally expanded to form a loop 11. which passes around the chute 6, and to the lower extremity of said lever l0 the feeding finger 1:5 is pivotcd, said finger extending toward the sealing head below the chute and being provided with a cross bar or stop pin 13 which lmugs'against the chute to limit the movenieit of the feeding finger Ainto the chute. A spring 13L is carried by the lever and bears upon the feeding finger to hold the linger to the chute. One end of the. cross bar 13 adapicfl to ride over 'a spring actuated wam 1f!- iiich is pivoted to a bracket 15 as at nionnlm'i o n the side of the chute, the ram being thus located in the path of the cross bar and being yieldingly held to the chute by a spring arranged in any convenient manner. An arm 16 is rigidly secured to one end of the shaft 9 and the free end 'of this arm 16 carries a roller 1T which is arrangedover and adapted to ride upon the upper edge of the lever 10 while rigid with the opposite end of the shaftl is a yoke 1S having inwardly extending flanges 19 at its upper and lower edges. Depending from the yoke is a barrel 20 containing a slidable plunger :2l which is normally projected under the influence of a coiledspring Q0 within the barrel. A lever Q2 is looselyvr .hung on the shaft 9 immediately adjacent the yoke 18 andpasses between the flanges 19, the outer end of this lever being pivoted to the upper end of a link 23 which has its lower end 'pivotech as at 2l, to a bracket 25 se cured on the standard 1.

A spring Q6 secured to the-chute and the lever 10 tends to draw the lever upward and a stop plate 27 is provided on the chute lo arrest said upward movement.

The caps are fed into the chute with the open side outward or downward. The chute being full of caps, when the machine is operated the sealing head descends and crimps a cap onto the hottie. "hen the sealing head descends. the arm 1b' is raised so that the roller 1i' is clear of the. hrcr l() which then drawn up against the stop 2T. by tln` spring Q13, the feeding' finger 12. of course. being carried upward with the lever. On this upward movement, the crosshar l will i ride over the outer surface of thc .rain 1land thefrce end oi' the finger will. conscqucntl'v, be witlnlrawn from ilsl engagement with a rap and will he out ot' engagement c y, ce L- t ie push lever does not begin p descend until the sealing head has nearly ipleted its return stroke andv the sealed is then entirely clear of the sealing lever Q2 rests 'upon the plunger 2l v' "ks against the spi 'iig in the barrel -e outer end of the lever 22 being red .to the upper end of the. link 23, the upward movement of the sealing head causes an upward and inivard movement of the ever 9.2 which is transmitted through the plunger and the barrel to the yoke 18. The yoke i8 being fast to the shaft- 9, said shaft ill loe rocked to lering the roller 17 against 'lever 10 and cause said lever to travel ov nivard against the tension of the spring o that the feeding nnger will n'iove vvard the sealing head. rlhe cap engaged hy the feeding linger Will he pushed toward the end of the chute and a new cap will he pushed into the sealinghead. The cross har on trie feeding linger bears against the chiite so that the finger can engage the cap only the proper-distance and on the down stroke e5 the cross loar passes under' the cam so that the finger remains in engagement with the cap during the entire stroke.

Should the operator, for any reason not place a bottle on the table of the machine, on the down stroke of the. sealing head, or remove the bottle before it is sealed,the push lever will move to its upper position asprev'iously explained and the feeding iinger Will` engage the cap behind the one previously engaged. `With a cap now in vthe sealing head and the chute full it Will he impossible to push another cap into place, and, heretofore, such condition would cause damage to the cap or the feeding mechanic'i, unless provision is ,made therefor.

lll n my apparatus, however, when the sealing head rises, the lever resting on the plunger 2l merely compressesthe spring in Y the barrel 20, the lever rotating about the shaft il vWithin the yoke 18 so that when the chute isfull of caps er is choked up ley a hrolren bottle neck or some foreign suh- ...nce which Will not allow the cap to loe shed into position, the motion of the lever "tf-*i up by the spring, but under normal CIL cdto the yoke and the caps fed as: he-

descrihed. Should a cap enter the nger will unable to entersaidcap which arl-and 'ons the motion of the lever is transLv ure in an inverted-(position, the feeding.

*my* f figurine i will,houseqiiently, he merely held in thc chute and cannot pass down thel chute and enter the scaling head.

.llaving thus -fully described my invention ulat l claim as new and desire to secure by Letters Patent is l ln a hottie. capping machine, the coinio'n "Witl'ra sealing'hea'd and a chute leaning thereto, of means for engaging and fccdinen caps successively through the chute to the scaling head, said means comprising a feeding linger, a push lever to which Said finger is pivoted, and mechanism including a .lost motion device. to oscillate said lever.
